I'm 51, 5'9" 180 and in really good shape fitness-wise. I do have a lot of aches and pains from years of sports and racing bikes. I can ride all day tank to tank for lots of days in a row. Used to do lots of 1000 mile days. I rarely do that anymore. I'm with ironmark life is too short. I like to take the road less travelled and stop check out the great things to be seen almost everywhere. That means 500 is usually about tops for me now. Stock ultra seat, backrest, highway pegs, madstad, 12" bars, beadrider, lots of Aleve or Advil.
